There's this big story and mystery behind the game, yawn, but basically you go to this island for some extreme games. While on this island, you can compete in five different events. These events include skyboarding, street luge, in-line skating, surfing, and skateboarding. There are a couple dozen different 'tracks' to compete on. You can also grab these special 'power-ups' along the way to give you an edge over your opponents.
The game plays pretty easily, and it's not really too involved. There is a Practice mode, as well as an Adventure mode. In this mode, as you win events, you learn more about the island. When you're done, you know the secrets of the island and it is no longer a mystery. How nice. I'm gonna have to say that the game was fun. It did get a little old, but it was fun while it lasted. I can't promise years of play, but you will enjoy it for a while.
